さてさて、ので、ここで私は私の質問でUINavigationControllerサブクラスに加えて、しなければならなかったものです。私が望むことを達成するためには、UIViewControllerAnimatedTransitioning代理人を使用しなければなりませんでした。
サブクラスNSObjectの2つのクラスを作成し、上記のプロトコルに準拠しています。
まず一つはUIViewControllerTransitioningDelegateプロトコルに準拠するために必要なこれのViewControllerを提示するだろうビューコントローラから次にdismiss transition-
import UIKit
class ComposeDismissTransitionController: NSObject, UIViewControllerAnimatedTransitioning {
func transitionDuration(using transitionContext: UIViewControllerContextTransitioning?) -> TimeInterval {
return 0.3
}
func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
let fromViewController = transitionContext.viewController(forKey: .from)!
let toViewController = transitionContext.viewController(forKey: .to)!
let screenBounds = UIScreen.main.bounds
var finalFrame = fromViewController.view.frame
finalFrame.origin.y = screenBounds.size.height
UIView.animate(withDuration: transitionDuration(using: transitionContext), delay: 0.0, options: .curveEaseIn,
animations: {
fromViewController.view.frame = finalFrame
toViewController.view.alpha = 1.0
}) { (finished) in
fromViewController.view.removeFromSuperview()
transitionContext.completeTransition(finished)
}
}
}
ためpresent transition-
import UIKit
class ComposePresentTransitionController: NSObject, UIViewControllerAnimatedTransitioning {
func transitionDuration(using transitionContext: UIViewControllerContextTransitioning?) -> TimeInterval {
return 0.6
}
func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
let fromViewController = transitionContext.viewController(forKey: .from)!
let toViewController = transitionContext.viewController(forKey: .to)!
let containerView = transitionContext.containerView
let screenBounds = UIScreen.main.bounds
let topOffset: CGFloat = UIApplication.shared.statusBarFrame.height
var finalFrame = transitionContext.finalFrame(for: toViewController)
finalFrame.origin.y += topOffset
finalFrame.size.height -= topOffset
toViewController.view.frame = CGRect(x: 0.0, y: screenBounds.size.height,
width: finalFrame.size.width,
height: finalFrame.size.height)
containerView.addSubview(toViewController.view)
UIView.animate(withDuration: transitionDuration(using: transitionContext), delay: 0.0, usingSpringWithDamping: 0.8, initialSpringVelocity: 1.0, options: .curveEaseOut, animations: {
toViewController.view.frame = finalFrame
fromViewController.view.alpha = 0.3
}) { (finished) in
transitionContext.completeTransition(finished)
}
UIView.animate(withDuration: transitionDuration(using: transitionContext), delay: 0.0, options: .curveEaseOut,
animations: {
}) { (finished) in
}
}
}
第二に、のためのものであり、 animationController:forPresentedとanimationController:forDismissedのような方法を実装します。
あなたは私のようなセグエ嫌いであれば、あなたは
IBActionからこれを行うことができ、
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
super.prepare(for: segue, sender: sender)
segue.destination.transitioningDelegate = self
}
- それが終わった後は210
extension PresentingVC: UIViewControllerTransitioningDelegate {
func animationController(forPresented presented: UIViewController,
presenting: UIViewController,
source: UIViewController) -> UIViewControllerAnimatedTransitioning? {
return ComposePresentTransitionController()
}
func animationController(forDismissed dismissed: UIViewController) -> UIViewControllerAnimatedTransitioning? {
return ComposeDismissTransitionController()
}
}
は、PresentingVCはprepareForSegueで行われていたUIViewControllerTransitioningDelegateからselfを設定するために必要なコード内のすべてのボタンも。これだけ
@IBAction func composeTap(_ sender: Any) {
let composeVC = self.storyboard?.instantiateViewController(withIdentifier: "compose") as! ComposeNavigController //this should be the navigation controller itself not the embedded viewcontroller
composeVC.transitioningDelegate = self
self.present(composeVC, animated: true, completion: nil)
}
ボタンがモーダルメール作成画面を提示するためにタップされた時はいつでも...今、それはモーダルで、私は望ましい効果でアニメーション化するでしょう。ちょうど楽しみのためにちょうど楽しみをちょうど加えた効果を加えました:)
